CSD Registration South Africa 2026: Complete Step-by-Step Guide

Updated May 2026. The Central Supplier Database (CSD) is the entry point for every South African supplier that wants to bid on government tenders. This guide covers everything: what the CSD is, exactly what documents you need, the step-by-step registration process, common rejection reasons, and how to keep your profile compliant year-round.

What Is the CSD?

The Central Supplier Database (csd.treasury.gov.za) is National Treasury's unified supplier register, mandatory for all organs of state since 1 April 2016. Before the CSD, each department maintained its own supplier list — which meant suppliers had to register separately with every department they wanted to work with. The CSD collapsed this into one profile that every government buyer can verify in real time.

What the CSD checks automatically:

• CIPC company status (active vs deregistered)
• SARS tax compliance (TCS PIN validity)
• Banking details (account holder match)
• Director/member ID verification against Home Affairs

When a department awards a contract, procurement officials pull your CSD profile on the day of award. If any check has lapsed, the award is blocked — regardless of how good your bid was.

Who Needs to Register?

All suppliers bidding on national, provincial, or municipal government tenders must be CSD-registered. This includes:

• Private companies (Pty Ltd), close corporations (CC), and sole proprietors
• Partnerships, trusts, and NGOs receiving public funding
• Joint ventures — each entity in the JV registers separately; the JV then references all CSD numbers in the bid

SOEs (Eskom, Transnet, PRASA, etc.) are not mandated to use the CSD but most now align their procurement to it voluntarily.

Documents Required

For a Company or Close Corporation

For a Sole Proprietor

• SA ID document (certified)
• SARS income tax number
• Banking confirmation letter (original, ≤ 3 months old)
• Proof of address

Step-by-Step Registration Process

Step 1: Gather Documents Before You Start

Do not start the online process before every document is ready. The CSD session times out after inactivity and partial captures must restart. Having everything prepared means you complete the process in one 30–60 minute sitting.

Step 2: Create a Login on csd.treasury.gov.za

Go to csd.treasury.gov.za → Register. You need a valid email address. This email receives all status notifications, including rejections and approval. Use a permanent business email — not a personal Gmail that a departing employee might lose access to.

Step 3: Select Supplier Type

Choose between:

• Organisation — Pty Ltd, CC, public company, NGO, trust
• Individual — sole proprietor, consultant

Choosing the wrong type requires a support ticket to correct. Organisation registration links to CIPC records automatically.

Step 4: Enter Company Details

Enter your registration number exactly as it appears on your CIPC certificate — including the K-number format for older CCs (e.g., CK1999/012345/23) and the 2014/123456/07 format for Pty Ltd companies. The system does a live CIPC lookup; a mismatch fails immediately.

Fill in:

• Registered name (must match CIPC exactly)
• Trading name (if different)
• Physical address (not a PO Box)
• Contact details

Step 5: Add Directors/Members

Each director or member must be captured individually. The system verifies each ID number against the Home Affairs database. Common issues:

• Name spelling on ID differs from CIPC director record → contact CIPC to correct
• Foreign national directors → passport verification takes longer

Step 6: Enter Banking Details

Capture your company's primary bank account. A banking confirmation letter matching these exact details must be uploaded. The CSD sends a small verification deposit (R0.01) to the account — you must confirm the deposit amount within 5 business days or the verification fails and must be restarted.

Banks that issue digital confirmation letters (FNB, Standard Bank, ABSA, Nedbank, Capitec Business) are accepted, provided the letter is on official letterhead and includes account number, account holder name, and branch code.

Step 7: Upload Supporting Documents

Upload clear, legible scans:

• All director ID copies (both sides)
• Banking confirmation letter
• SARS TCS PIN (if applicable)
• B-BBEE certificate

PDF format is preferred. Scans below 300 DPI are frequently rejected as unreadable. Colour scans of IDs verify security features better than black-and-white.

Step 8: Submit and Monitor Status

After submission the CSD runs automated checks against SARS, CIPC, and Home Affairs. Status moves through:

1. Pending — initial submission received
2. In Review — automated checks running (1–3 business days)
3. Active — registration complete; your CSD number is issued
4. Rejected — one or more checks failed; email notification with reason

Check your email and the CSD portal daily during this period. Rejections that are not corrected and resubmitted within 30 days require a full restart.

Most Common Rejection Reasons

Keeping Your CSD Registration Active

CSD registration is not a once-off. Your profile becomes non-compliant automatically if:

• SARS TCS PIN lapses — the most common cause; happens when a return is missed
• CIPC annual returns are not filed — CIPC deregisters companies that skip 2 years of returns
• Banking details change — update within 30 days of any account change
• Director changes — add new directors; remove resigned ones

Best practice: Set a quarterly calendar reminder to log in to csd.treasury.gov.za and verify your status is still Active. Do the same check on csd.treasury.gov.za under the "Profile" tab before submitting any major bid.

CSD and B-BBEE

Your CSD profile includes your B-BBEE level, but the CSD does not verify B-BBEE certificates — it only stores what you upload. Government departments verify B-BBEE certificates separately against the SANAS-accredited verification body that issued the certificate. Keep your B-BBEE certificate or EME/QSE affidavit current and upload the latest version to your CSD profile each time it renews.

After Registration: What's Next

Once your CSD number is active you are eligible to bid on any government tender in South Africa. Your next steps:

1. Register on the eTenders portal (etenders.gov.za) to download bid documents
2. Set up a ProTenders free alert to receive daily new tenders matching your categories
3. Build your bid pack: company profile, CIDB grade (construction), PSIRA certificate (security), or other sector-specific credentials

ProTenders includes a compliance checklist in the Business Workspace to track certificate expiry dates across CSD, SARS, CIPC, and B-BBEE — so no renewal sneaks up on you before a tender deadline.
